Brake Lines Suck!!

[toofun]

Bought all new brake lines, combination valve, master cylinder, and hydroboost. Connected everything together and for the life of me I cant get my friging brake lines to stop weeping fluid. From what I can tell it is only the main back brake line and the line going from the back of the master cylinder into the combo valve as well. ALL THE FRIGING LINES ARE NEW AND THEY STILL *&%$#@ LEAK!! Is there something I can put on them to help? How about thread sealer? I know it is a compression fit but this is ridiculous. EVERYTHING IS NEW!! Any help would be appreciated. I AM REALLY STARTING TO HATE BRAKES!!!
